Frankly I do not know how the system works in the technological sense. I have near zero experience or expertise with coding or website formatting.
So on that note, I would like to hear how an optional system could be introduced to DU. -Not as in 'tell me, while I sit smugly laughing at your lack of expertise', but genuinely as in 'how does it work'?
That way I can sidestep any conversation about the system, where I give vague reasons for its existence, and instead on focus on the topic of implementation of such options.
Seeing as some people just don't vote in elections, it seems reasonable that DU should allow users to opt-in or opt-out of some features. (An example of a system; elections, primarily democracy in mind, where pleasing everyone is near impossible! Though it is possible to please no one with a decision it seems.)
Though at the end of the day it is not strictly within my ability or capacity to change the website. That honour lays with the Webmistress; not trying to point fingers or shirk responsibility, just be transparent.
I don't believe I have all, if any, of your answers, Viddax. But since I was the one to mention the Dewey system as an example of international classification, let me share in brief how that works. I've simply copied some material that I am going to paste here for your information. I make no claim to the verity or ownership of the data.
Dewey Decimal system
"The Dewey Decimal system is a classification system used by libraries to arrange books via subject. Each book is issued a shelfmark number, usually found on the spine of the book, and arranged in numerical order.
"The first three digits refer to broad subject area, and are shelved in numerical order e.g. 945 is shelved before 946.
000 Computer science, information and general work
100 Philosophy and psychology
300 Social sciences
700 Art and recreation
900 History and geography
"After the three digits there is a decimal point and numbers after the decimal point show the sub-section of the subject area. Again they are shelved in numerical order e.g. 945.805 is shelved before 945.81.
After the numbers there are three letters which refer to the author or editor of the book and are in alphabetical order e.g. 945.805 TAB is shelved before 945.805 TRB.
"Note: Journals (also called periodicals) always start PER, followed by three numbers and then the first three letters of the journal series e.g. PER720 ARC. Medical journals follow the same ordering, but start MED PER."
